A QR code on screen, and the answers come in.
A QR code on screen, any browser, and everyone joins, from the front row to the back of the room. No app to install, no account to create.


A graded quiz, in a different order for each student.
With Pro, in evaluation mode, each student gets the questions in a random order, with shuffled answers, on a timer. The grade is calculated at the end.
Presentations follow one another, no cables.
With Pro, each student projects and controls their slides from their phone, with their own QR code. One talk ends, the next takes over — no more HDMI cable shuffle, and you grade live.

See what the room thinks, live.
Bar charts and word clouds build up on the projector as answers come in — and anyone can tap “I’m lost” without interrupting the lecture.
Wake up your next class, for free.
Free to start. Pro removes the 8-activities-a-month limit and adds evaluation mode and back-to-back presentations, on Mac — price on the Mac App Store.
